INTRODUCTION
Congratulations on your choice of the TUSA IQ-400 Dive Computer.The IQ-
400 is a compact and sophisticated dive instrument that will give you years of
trouble free and joyful diving. The IQ-400 dive computer will provide you
with important information that you will need during, between, and after your
dives.
Key Features
The IQ-400 monitors and reports vital information such as your dive time,
current depth, maximum depth, no-decompression time and ascent rate.
The IQ-400 will also give you information, if through carelessness or emer-
gency you are forced to exceed the no-decompression limits for any dive.
The IQ-400 has a built-in calendar and clock. It features versatile logbook
memory capabilities and long-term historical data. The instrument can be
adjusted for diving at different altitudes or to add an extra level of conserva-
tiveness if desired.
The screen is protected against scratches and damage by a replaceable shield.
The IQ-400 is available either as a wrist unit with an optional protective boot
or mounted in two gauge or three gauge console or in a hose mounted boot.
The modular construction allows for the separate compass module to be
attached to the two gauge console at a later stage.
